Make sure that your GP has correctly diagnosed. I suffered from a cavernous sinus infection about 15 years ago that presented at one point very much like Bells, but not quite . . . was only correctly diagnosed after 6 months of NHS investigation by visiting a US Navy diving medic who was also a neurologist; went through 2 CT scans, 2 MRI scans, a lumbar puncture and lots of other miscellaneous tests along the way. At one stage the NHS consultants suspected early-onset MS (very scary for a few weeks). Still have some minor facial muscular weakness and imbalance today, but major symptoms (such as 6 months of excruciating headaches and 2 months of double vision) created by the viral infection have thankfully never returned.
